Improvement in life-boats



PATENT rrron.

ROBERT I. ROBESON, OF OSKALOOSA, IOWVA.

Specification forming part of Letters Patent No. 117,817, dated August8, 1871.

To all whom "it may concern:

Be it known that I,'ROBERT I. RoBnsoN, of ()skaloosa, in the county ofMahaska and State of Iowa, have invented a new and useful Improvement inLife-Boats 5 and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanyin g drawing and the letters and figures marked thereon whichform a part of this specification, and in which Figure 1 represents aside elevation of my improved boat; Fig. 2, a vertical sectional view atthe lines .10 av in Fig. 1; Fig. 3, a transverse sectional view at theline y y in Fig. 1; and Fig. 4, a side elevation of one ofthe buoysdetached from the boat.

The nature of my invention consists in attaching to the top of a boatbuoys with air-chambers, and in constructing the buoys in separatecompartments provided with valves, and in making them readily attachableto and detachable from the boat, as hereafter more fully described.

To'enable those skilled in the art to understand how to manufacture anduse my invention, lwill proceed to describe the same with particularity.

The same letters of reference refer to the corresponding parts in thedifi'erent figures.

in the annexed drawing, A represents any ordinary boat constructed inany of the known styles, and B are pins or other suitable fasteningsattached to the sides of the boat for fastening thereto the buoys G. Thebuoys O are made in compartments, being separated by air-tightpartitions l). E are openings, one of which opens into each compartment,but each opening is covered with a valve, F, which prevents the waterfrom flowing into the compartments, but will admit of its fiowin g outwhen any happens from any cause to find its way into the buoy. H Hrepresent holes through which the pins, B pass to fasten the buoys tothe boat. They may be made by attaching straps or pieces to the side ofthe buoy. These buoys C may be readily removed 'from the boat by simplyraising them from the pins 13. The boat then is like any ordinary boat,excepting the devices that may be attached to its sides for securingthereto the buoys; but, when safety is desired, the buoys O are attachedas above described, there ordinarily being one for each side of theboat.

These buoys may be made of rubber or any other suitable material, andthey may be filled with air or gas, or anything lighter than water, soas to keep the boat above water and prevent it from dipping water. Theywould accomplish the same result whether put on the outside or inside ofthe boat near its top edge.

I claim- The hollow buoys 0, provided with partitions D and valves F,-incombination with the boat A, when the said buoys are made attachable anddetachable, in the manner shown and described, substantially asspecified.

R. I. ROBESON.
